You may be right, but this isn't a helpful comment. Per the HN guidelines [0]:
Be kind. Don't be snarky. Comments should get more
thoughtful and substantive, not less, as a topic
gets more divisive.
When disagreeing, please reply to the argument
instead of calling names. "That is idiotic;
1 + 1 is 2, not 3" can be shortened to "1 + 1
is 2, not 3."
Please don't post shallow dismissals, especially
of other people's work. A good critical comment
teaches us something.
